Molten Chocolate Chunk Cookies Step-by-step instructions

Before you start

Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper. Measure all ingredients accurately. Have the butter melted and slightly cooled, and ensure the eggs are cold straight from the fridge.

Whisk the dry ingredients together in a bowl to eliminate any lumps. Set up the stand mixer with the paddle attachment. Prepare a 4-ounce cookie scoop for even portions.

Instructions

Mix the Dough

1. 1Mix the Dry Ingredients
   In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and cornstarch until evenly combined. Set aside.
   Look for The dry mixture should look uniform with no streaks of cocoa.
   Tip Whisking aerates the flour and distributes the leaveners.
2. 2Cream Butter and Sugars
   In the bowl of a stand mixer fitted with the paddle attachment, beat the melted butter, brown sugar, and granulated sugar on medium speed until smooth and glossy, about 2 minutes.
   Look for The mixture should look like a thick, shiny paste.
   Tip Use cold eggs to help the dough firm up.
3. 3Add Eggs and Vanilla
   Add the eggs one at a time, beating well after each addition. Then add the vanilla extract and beat until fully incorporated.
   Look for The batter should be smooth and slightly pale.
   Tip Scrape down the sides of the bowl to ensure even mixing.

At the end of this phase, the dough should be thick, glossy, and well combined. The dry ingredients should be fully incorporated with no visible flour streaks.

The chocolate chips should be evenly distributed. The dough should hold together when pressed, and it should be firm enough to scoop into balls without collapsing.

Shape and Top

4. 4Combine Wet and Dry Mixtures
   With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Beat just until no streaks of flour remain. Do not overmix.
   Look for The dough will be thick and cohesive.
   Tip Overmixing can develop gluten, making cookies tough.
5. 5Fold in Chocolate Chips
   Gently fold in the chocolate chips with a spatula until evenly distributed throughout the dough.
   Look for The chips should be scattered throughout the dough.
   Tip Reserve a few chips to press on top of the dough balls.
6. 6Scoop Giant Dough Balls
   Using a 4-ounce cookie scoop, portion the dough onto a parchment-lined baking sheet, spacing them about 3 inches apart. Press extra chocolate chips onto the tops of each dough ball.
   Look for The dough balls should be large and round.
   Tip Chilling the dough for 30 minutes can help prevent spreading.

The dough balls should be large, about 4 ounces each, and evenly spaced on the baking sheet. Pressing extra chocolate chips on top ensures visible molten pools. The dough balls should be round and slightly domed. The baking sheet should be fully lined with parchment paper to prevent sticking.

Bake to Perfection

7. 7Bake the Cookies
   Bake in a preheated 350°F (175°C) oven for exactly 12 minutes, until the edges are set and the tops are slightly cracked.
   Look for The edges look firm, but the centers may still appear soft.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Do not overbake; the centers will set as they cool.
8. 8Cool and Serve
   Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack. Serve warm to enjoy the molten chocolate pools.
   Look for The cookies will be soft and fragrant.
   Tip Warm cookies are best for that gooey effect.

The cookies should have set edges and cracked tops. The centers will look soft and slightly puffed. The aroma of chocolate and butter will fill the kitchen. The cookies should be lightly browned around the edges but still pale in the center. They will be delicate and may sink slightly as they cool, which is normal.

Common mistakes

One common mistake is overmixing the dough, which can develop gluten and result in tough cookies. Mix just until the flour is incorporated. Another issue is overbaking, which dries out the cookies and eliminates the molten center.

Keep a close eye on the timer and remove the cookies when the edges are set. Also, avoid using warm eggs, as they can make the dough too soft and cause spreading.

How to tell it’s done

The cookies are done when the edges are set and lightly browned, but the centers still look slightly soft and underdone. This is the desired state, as the residual heat will continue to cook the centers while they cool.

The internal temperature of the cookies should reach at least 160°F (71°C) to ensure the eggs are fully cooked. They will firm up as they cool but remain fudgy and moist.
